Abstract
The invention relates to a tunnel kiln sealing structure. A tunnel kiln body is in clearance sliding contact with a fire-resistant brickwork arranged on a kiln car frame. The tunnel kiln sealing structure is characterized in that an elastic fire-resistant layer is arranged in the clearance. The elastic fire-resistant layer is added in the clearance between the tunnel kiln body and the brickwork on the kiln car frame, the elastic fire-resistant layer is in frictional contact with the corresponding tunnel kiln body (or the kiln car brickwork) when a kiln car moves, and the elastic fire-resistant layer with a certain elasticity expands in the clearance of different sizes, so that the kiln car is in close contact with the tunnel kiln body, fluctuant air flow of the kiln car is prevented from flowing, the fluctuant temperature differences in the kiln in a preheating zone are decreased, damage of the kiln car is reduced, and firing quality of products is improved.
Description
Technical field
The present invention relates to a kind of tunnel cave, relate in particular to the hermetically-sealed construction in the tunnel cave.
Background technology
The tunnel cave that pottery, refractory material, brick-tile industry burn till, burn product and earlier outside kiln, load onto kiln car, the kiln car that product will be housed then advances in the kiln and burns till, general temperature all will be more than 1000 ℃.Because kiln car must move,, promptly keep the gap about 20mm between kiln car and kiln body, but the sealing effectiveness of this structure is unsatisfactory so adopt tortuous cross structure to seal between kiln car refractory material and the kiln body in kiln; Because the expansion of kiln car refractory material masonry is shunk, can cause kiln car refractory material masonry loosening simultaneously, cause the inconsistent phenomenon of bent envelope gap length.
Because the inherent characteristic of tunnel cave; The preheating zone is generally negative pressure; High temperate zone is a malleation, and the kiln car sealing is bad will to cause the interior back of cold wind entering kiln upper and lower temperature difference considerable influence product quality under the car of preheating zone, and high-temperature gas flows downward in the kiln of high temperate zone; Burn out the kiln car metallic material components, cause card kiln, kiln collapse accident.
Summary of the invention
The present invention has overcome deficiency of the prior art, and a kind of tunnel cave hermetically-sealed construction of good sealing effect is provided.
Technical scheme of the present invention is following:
A kind of tunnel cave hermetically-sealed construction, said tunnel kiln body and being located at are the gap and slide and touch state between the refractory masonry on the kiln car vehicle frame, be provided with the elasticity flame retardant coating in the said gap.
As improvement, said tunnel kiln body and the gap of being located between the refractory masonry on the kiln car vehicle frame are 15-30mm.
As improvement, described elasticity flame retardant coating is a refractory fibre.
The gap location of the refractory masonry on kiln body and kiln car vehicle frame adds the elasticity flame retardant coating, and the elasticity flame retardant coating produced CONTACT WITH FRICTION with corresponding kiln body (or kiln car masonry) when kiln car moved, because the elasticity flame retardant coating has certain elasticity; Gap location in different sizes can produce flexible; Be in tight contact condition thereby make between kiln car and the kiln body, downstream is mobile on the prevention kiln car, reduces the upper and lower temperature difference in the kiln of preheating zone; Reduce the damage of kiln car, improve the quality of burning till of product.
Description of drawings
Fig. 1 is the partial schematic diagram of tunnel cave and kiln car hermetically-sealed construction.
Wherein: 1 is tunnel cave, and 2 is the tunnel kiln body, and 3 is the kiln car vehicle frame, and 4 is refractory masonry, and 5 is elastic fire resisting material.
The specific embodiment
Further specify the present invention below in conjunction with accompanying drawing.
Referring to Fig. 1, the kiln car in the tunnel cave 1 comprises kiln car vehicle frame 3 and is positioned at the refractory masonry 4 on the kiln car vehicle frame 3, is the gap slip between tunnel kiln body 2 and the refractory masonry 4 and touches state, and said gap is 15-30mm, is preferably 20mm; In the gap, be provided with elasticity flame retardant coating 5, described elasticity flame retardant coating 5 can be selected from refractory fibre.
The elasticity flame retardant coating produced CONTACT WITH FRICTION with corresponding kiln body (or kiln car masonry) when kiln car moved; Because the elasticity flame retardant coating has certain elasticity, can produce flexiblely at the gap locations of different sizes, be in tight contact condition thereby make between kiln car and the kiln body; Downstream flows on the prevention kiln car; Reduce the upper and lower temperature difference in the kiln of preheating zone, reduce the damage of kiln car, improve the quality of burning till of product.
Hermetically-sealed construction of the present invention also is applicable between other kiln body and kiln car that adopts kiln car class kiln simultaneously.
Claims (3)
1. tunnel cave hermetically-sealed construction, said tunnel kiln body and being located at are the gap and slide and touch state between the refractory masonry on the kiln car vehicle frame, it is characterized in that being provided with in the said gap elasticity flame retardant coating.
